Hi,
there is a new version of the pvrinput plugin available: http://home.arcor.de/andreas.regel/files/pvrinput/vdr-pvrinput-0.1.0.tgz
With this version ivtv 0.4.1 should work too, I just had to extend the probing routine to find the card(s).
Changes since 0.0.9: - fixed detection of pvr card to work with ivtv version 0.4.1 or later
